GX345   QUESTION: John,
Thank you so much for your time.  The knob moves well along w/the cam, it's that the cam is not 'hitting anything' to change the height (i think) [it is really hard to see up in there with the plate covering the cam]  am i correct in thinking that the cam should move the lever in the middle of the 'mid lift'shaft?  I have scanned a copy of the page you recommended, and written on it, basically what i just said.  
Thanks again,

Answer
Hello Again Timmye:

>>The Only Time the Cam Engages/Touches Anything (the Mid-Lift Shaft #10) is when the Deck is Lowered.
>>The Cam is Sets so the Mid-Lift Shaft (#10) can Only Lower Until Mid-Lift Shaft Engages/Touches the Cam Lobe.
>>The Depth Stop is Supposed to be Set Only with the Deck in the Raised Position.
>>As Always, If you Hit a Snag or this Does Not Correct the Problem,  I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
